Description

The LMR38010 synchronous buck converter is

designed to regulate over a wide input voltage range,

minimizing the need for external surge suppression

components. The LMR38010 operates during input

voltage dips as low as 4.2 V, at nearly 100% duty

cycle if needed, making the device an excellent

choice for wide input industrial applications and

MHEV/EV systems.

The LMR38010 uses precision enable to provide

flexibility by enabling a direct connection to the

wide input voltage or precise control over device

start-up and shutdown. The power-good flag, with

built-in filtering and delay, offers a true indication of

system status, eliminating the need for an external

supervisor. The device incorporates pseudorandom

spread spectrum for minimal EMI and switching

frequency can be configured between 200 kHz and

2.2 MHz to avoid noise sensitive frequency bands. In

addition, the frequency can be selected for improved

efficiency at low operating frequency or smaller

solution size at high operating frequency.

The device has built-in protection features such as

cycle-by-cycle current limit, hiccup mode short-circuit

protection, and thermal shutdown in case of excessive

power dissipation. The LMR38010 is available in an

8-pin HSOIC PowerPAD integrated circuit package.
